SPECIFICATION forming part of Letters Patent No. 609,300, dated August 16, 1898. Application filed September 10, 1897. Serial No. 651,237, (No model.)

T all whom it may concern:

Be it known that LEMMETT J. SATTERWHITE, of Falls City, in the county of Richardson and State of Nebraska, have invented a new and Improved Vinding-Machinepf which the following is a full,clear,and exact description.

My invention relates to machines for winding wire on a core for forming electromagnets; and its object is to provide a new and irnro proved winding-machine arranged to accurately wind the desired amount of wire on a core of the desired length.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indizo cate corresponding parts in all the'igures.

Figure 1 is a plan view of the improvement. Fig. 2 is a sectional side elevation of the same. Fig. 3 is a transverse section of the same on the line 3 3 of Fig. l. Fig. 4 is an enlarged cross-section of the guide or carrier and adjacent parts, and Fig. 5 is a sectional side elevation of the same.

The improved winding-machine is mounted on a suitably-constructed frame having a base 3o A and a standard A', in which is journaled a spindle B, provided at one end with a crankarm B' or other means for turning the said spindle. The inner end of thespindle B is y formed with a center B2 for engaging a core 3 5 or spool C, j ournaled at its other end in a center D, held in a standard D', longitudinally adjustable in guideways A2, secured to the top of the base A.

On the spindle B is formed or secured a 4o flange B3, adapted to be locked to the liange of the core C by a set-screw B4 or other suitable means, (see Fig. 1,) so that when the spindle B is rotated a rotary motion will be given to the spool C for winding up the Wire E, unwinding from a bobbin F, held on centers F and F2, of which the former is mounted in the standards A', and the other center F2 is mounted in a standard F3, held longitudinally adjustable in guideways A8, attached to the base A opposite the guideways A2.

The wire E, While passing from the bobbin F to the core C, is engaged bya guide or carrier G, mounted to travel forward and back- Ward, so asto lay the fwire in successive layers on the core C, according to the distance between the anges of the said core. The guide or carrier G is mounted to travel longitudinally on screw-rods H and H', located one above the other and journaled in suitable bearings in the standards A' and in a stand- 6o ard A3, attached to the base A.

Between the screw-rods H and H is arranged a double nut I, formed with threads I I2, of which the upper thread I is adapted to engage the threads on the screw-rod II, and the lower thread I2 is adapted to engage the threads on the screw-rod H'. The double nut I is fitted to slide` up and down `in suitable guideways G',`for1ned,in the guide or carrier G, as is plainly shown in Figs. 4L and 5, and 7o thesaid nut I is held on a pin J, extending through elongatedslots in the guide G to connect at its outer ends with arms J', secured to a shaft J2, journaled in suitable bearings in the guide Gr.

One of the arms J has an extension, as is plainly shown in Fig. 3, and this extension is pivotally connected bya link J 3 with one end of a lever K, fulcrumed at or near its middle, at K', to the lower end of the guide Gr. 8o The ends vof this lever K are rounded oft', as plainly shown in Figs. 2 and 5, and are adapted to be alternately engaged by stops L L', secured by set-screws onl a shaft L2, mounted to turn in suitable bearings in the standards A' and A3. On the shaft L2 is formed a graduation L3 for setting the stops L L', according to the distance between the iianges of the core C, on which the wire is to be wound in layers of a length corresponding to the distance be- 9o tween the said iianges.

Now when the several parts are in the position shown in Fig. 2 and the guide Gris travcling in the direction of the arrow d', this movement being caused by the nut I being in engagement with the lower screw-rod H', then the forward end of the lever K will iinally be engaged by the stop L, so that the lever receives a swingingy motion and draws the link J 3 downward and causes a swinging roo of the arms J to move the nut I out of engagement with the screw-rod H' and into engagement with the screw-rod H. As the screwrods H and H turn in opposite directions it is evident that the nut I is caused to travel in the reverse direction of the arrow a, and as the said nut is held in the guide G the latter will always move in the reverse direction of the arrow c. Vhen the guide G is moved to the left, the lever K finally moves into engagement with the stop L, so that a swinging motion is again given to the said lever K, but in an opposite direction, so as to move the nut' I out of engagement with the screwrod H and againV into Vengagement with the screw-rod H. The nut I and guide G will now again travel in the direction of the arrow a', and the above-described operation relatively .to thel alternate travel forward and backward of the guide G is repeated.

Thescrew-rods H and I'I rotate in unison, and. for this purpose I provide gear-wheels H2 H2, secured on the rods H and H' and in mesh with each other. On the screw rod H is also secured a gear-wheel H4 in mesh with the gear-wheel N, secured on a stud N- and :rigidly connected with a -larger gearwheel N2 in mesh with a pinion B4, secured on the spindle B. Thus when the latter is rotated a rotary motion is given to the core C andv at thesame time to the gear-wheels N, N2, and H4 to rotate the screw-rod Hl and also torotate the screw-rodII, but in an opposite direction, by the gear-wheels H3 and H2. The shaft L2 is likewise simultaneously rotated with the screw-rods H and II', and for this purpose thescrew-rod II is provided with a gear-wheel H5 in meshvwith a gear-wheel L4, securedv on the said shaft L2.

Wfhen windin g wire of a different thickness, it is necessary that a different rate of speed shall be given to the guide G from that given to the core C, and for this purpose I make the connection between the pinion B4 and the gear-wheel H4 interchangeable by substituting different-sized gear-wheels for the gearwheels N and N2. In order to permit such a change, I make the stud N adjustableon a frame N2?, adjustably held on the standard A. This frame N3 is provided for this purposewith a slotted arm N4, in which the stud N'. is adjustably secured, and with a slotted segment N5, secured by bolts NG to the standard A. By mounting different-sized gearwheels N N2 on the stud N', I adjust the'latter in the slotted arm N4 and the said arm on bolts N6 until the gear-wheels N VN2 con-- nect the pinion B4 and the gear-wheel H4 with each other.

The guide G for carrying the wire A is provided on one sidenext to the bobbin F with friction-rollers G2 G3, under which and overl which passes the wire from the said bobbin F to and over a pulley G4, j ournaled in the top of the said guide G.

laterallybetween the rollers G5 and G4, ofl which the former is journaled in fixed bear- The wire then passes ings in the guide G, and the other roller G6 is journaled in adjustable bearings likewise held on the guide G, as is plainly indicated in Fig. 3. This adjustment is necessary for different-sized wires to be wound on the core C. Now in order to indicate the length. of the wire wound upon the bobbin F, I provide the guide G with a tally arranged as follows: lOn the shaft G7 of the pulley G4 is secured a tooth O in mesh with a gear-wheel O, mounted to rotate loosely on a stud O2, secured to the guide G. On the face of the gear-wheel O is formed a graduation O3, indicating feet, yards, or like linear measurement, and on the said graduation indicates a fixed pointer O4, `secured on the stud O2. A ratchet-wheel O5 is attached to the stud O2 and is engaged by a spring-pressed pawl O6, fulcrumed on the gear-wheel O', adapted to prevent the return movement of the indicating gear-wheel O'.

Nowon every revolution of the pulley G4, which is caused by the traveling wire E, the gear-wheel O' is moved the distance between two teeth, so that the pointer O4 indicates the length of the wire that passed over the pulley G4 during one revolution, the amount being read on the graduation.

Now it will be seen that by the arrange-- ment described the wire E is wound on the core C from the bobbin Fand is properly placedin position on the core by the traveling guide G, which moves forward or backward whenever a layer is completed, and at the same time the amount of wire placed on the core is indicated by the pointer O4-on the graduation O2, so that the machinecan be readily-stopped when the desired amount ofv wire has been placed on saidcore. The core is then detached from the centers B2 and D, and a newempty core is put inposition thereon, after which the wire is again fed'upon this core in the manner above described.

Having thus fully described my invention,
